PUMPING- APPARATUS.

1 ,089,955. I Application filed To all "whom it may concern Be it known thatl, .Aaiuni. J. PE'rnnsoN, a citizen of the United States, residing at- State o't' tleorgia, have invented new and useful Iniprov(, n'ients in Pumping Appa- 1atus, -o't \\'lll(ll the following is'a specifica- 'lhisinvent ion relates to new and useful improvements in pumping apparatuses and ratus intended especially for use in lighting cases where a pump may be desirable for the ordinary or usual purposes. l

Theinvention proposes to combine with. a water pump, an air pinup which maybe driven from the same prime mover as the water pumpfan'd which assists the mechanical action of the latter in'discharging the *water, eausingthe'strcam to have an increased speed and force. Y

It is a well known fact that a great deal 'of the power employed in conducting water is expended in overcoming friction which is chiefly incident to the non-elastic nature of Water and the present invention proposes lusage of power which ordinarily is wasted n overcoming friction, by maintaining and providing for the maintenance of an expans'ible, elastic water forcing agent in connection with the water pump. The water pump is thus employed to complete one stage of the water forcing operation while the body of elastic fluid under compression is employed to complete the final stage of the water forcing operation. To

this manner the capacity of the machine as an entirety is materially-increased, since the bod of air which completes the final stage 0 the Water forcing operation, operates-with less friction and less .waste of circumstances. In the accompanying drawings I have illustrated a preferred and advantageous embodiment of, the invention. In thesaid drawings: Figure 1 is a side elevation of an apparatus constructed in accordanee with the present invention. i t 2 is .a top plan view thereof, and Fig. 3 s a detailplan view of the compressor tanks Specification of Letters Patent.

corresponding partsthroughout the several views. i

As shown in Fig. 1, the apparatus is mounted on a suitable supporting frame 1 and consists essentially of a prime mover, as forcxample, a steam engine, 2, an air pump, 3, and a water amp, 4. For co'nvenience, the crank shaft 5 of the engine 2, is employed to drive the pump This arpngement is not to be considered as ob ligatory, however. The pump 3 may be of any approved form and'in the embodiment shown, is employed to charge a pair of air compressiontanks, 6, intowhich air flows from the pump 3 through a connection pipe '7, the latter having a suitable check valve,

8, therein. The crank shaft 5 is also eniployed to operate the pump t and accordingly said shaft has at its ends oppositely extended crank arms to which are connected links, 9, the latter being in turn conncct ed to levers 10. The levers 10 are pivoted intermediate their lengths and at their lower ends are opcrativcly connected to the extended piston rods ll of the pump '4, the latter being preferably of the well known duand being surmounted by a water tank ]2,-prov1ded with an air dome thc other of said tanks a pipe, as 15, leads.

is provided with a suitable The pipe 15 and has a branch. 17, which check valve, 16,

opens into the upper portion of the tank 12- and also a branch, 18, which opens into the discharge pipe 14.

In operation the pump 4 forces water into the tank 19 from whence it is violently discliarged by the column of air confined in the dome 13 and also by the action of the wipe 14-. The pump L is thus allowed to worlt at its maximum speed in charging the tank 12 with water, the discharge of which from said tank is eti'ected by. air, with less waste of power than would be the case it the pump t were relied on for this purpose. v

.The tank 12 has been shown in the drawingssnialler in proportion to the size of the pump 4 than it will be in tlCl'llfll'pItlCtlCB, the scale of drawings -having been adopted for the purpose of convenience A water discharge pipe, 14, leads from of illustration only. it will, therefore, be understood that; airaione may be employed to force water from the tank 12 in the event of the pump 4 becoming deranged or of its action oeing stopped.

1 it will be understood that the inachine may be constructed for use in connection "with stationary systems or it may be of portable nature.

Having an described my invention, I

reclaim:

In a pumping apparatus, the combination of a'Water-pump; a receiving tank in communication {therewith and having an air dome; a water-discharge pipe leading from said tank; an air pump structurally independent of the Water pump; a compressed airv reservoir, a pipe connecting said reservoir and said air pump; a pipe connecting discharge pipe for supplying compressed air to faciiitate the dis-.

to said discharge pipe charge of Water from said tank.-

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
